Abstract
Description
Gegenstand dieser Neuorung sind Damm- und Deich-Befestigungsmatten mit Filterwirkung.The subject of this innovation are dam and dyke fastening mats with filter effect.
Die Grundanmeldung hat zum Gegenstand "Mattenförmige, lockere Flore zur Befestigung von Dämmen, Deichen urd Böschungen usw., die au chemisch neutralen Kunststoff-Fasern bestehen, die mit einem seewasser- und chemikalienbeständigen Klebe; verbunden sind. Sie können durch aufgelegtes oder eingearbeitetes Gittergewebe oder Fäden verstärkt.sein und können einseitige Materialverdichtung aufweisen o&Ier gar ganz zu einem dünnen Flor Preßflor zusammengewalzt sein und angeklebte Samenkörner aufweisen.The basic application has the subject "mat-shaped, loose pile for fastening dams, dikes and embankments, etc., which are also chemically neutral Plastic fibers are made with a seawater and chemical resistant Glue; are connected. You can do this with a laid-on or integrated mesh fabric or threads are reinforced and can have one-sided material compression o & Ier be completely rolled up into a thin pile of pressed pile and glued-on seeds exhibit.
Durch die erste Zusa zanmeldung (Akt. Zch. P l8oo.243. 2) sollen diese Matten eine weitere Verstärkung crfahren durch eine den Flor stellenweise verdichtendc Prägung und eine Beschwerung bekommen durch spezifisch schwere Füllstoffe.With the first additional registration (file Zch. P 18oo.243. 2) these Mats provide additional reinforcement by compressing the pile in places Embossing and weighting are given by specifically heavy fillers.
Durch die Profilierung wurde erreich, daß aufgewirbelter Sand besser zurückgehalten wird.The profiling made it possible to improve the sand that was blown up is held back.
Nun hat sich aber gezeigt, daß diese Form Qui Verd chtung dann noch nicht genügt, wenn eine Wasserbewegung durch eine Schiffsschraube oder Stürme vorübergehend einen hohen Druck desjenigen Wassers erzeugt, welches über den Wasserspiegel aufs Ufer gelangt und stoßweise zurücicfließen will. Dieser Wassersteß sowohl von der Wasserwie auch VOÄ der Landseite her lockert fortgesetzt das Erdreich so, daß kleine Partikel immer wieder ausgespült werden, besonders dort, wo der Flor eine gringere Dichte hat. Das auf den Flor aufgelegte, an sich verscheißte Gittergewebe aus Chemiefasern nach der Grundanmeldung hat zwar ein gutes Iiückhalt ovcrniögun, doch hat sich gezeigt, daß das Gewebe selbst durch die fortgesetzte Reibung des Sandes vom Flor a mählich gelöst werden kann, wodurch die gute Wirkung beeinträchtigt wird.It has now been shown, however, that this form of qui then still proves suspicion not enough if a water movement caused by a ship's propeller or storms is temporary creates a high pressure of the water that rises above the water level Reaches the bank and wants to flow back in spurts. This water rush from both the Water as well as VOÄ on the land side continues to loosen the soil so that small ones Particles are rinsed out again and again, especially where the pile is a little larger density Has. The woven fabric made of synthetic fibers and laid on top of the pile according to the basic registration, although there was good support, it has been shown that that the fabric itself becomes gradual as a result of the continued rubbing of the sand with the pile can be dissolved, thereby impairing the good effect.
Nouerungsgemäß wird nun zur Behebung dieser Mängeß vorgeschlagen, das an sich verschweißte Gittergewebe in den Flor so einzunadeln, daß ein großer Teil der Chemiefasern durch das Gittergewebe hindurchtritt und auf der Rückseite einen schlingenförmigen zweiten Flor bildet, wie man dies in ähnlicher Weise von den bekannten Tuftetbindungen her kennt. Durch die anschlicßende Besprühung mit einem seewasser- und oder einearbeitete SchmelzfasernX chemiknlienfesten BinderIwiru eine große Haltbarkeit erzielt. Statt des Gittergewebes kann auch mit Erfolg ein Preßflor aus Chemiefasern benutzt werden.According to Nouer, it is now proposed to remedy this deficiency, to needle the welded mesh fabric into the pile so that a large Part of the man-made fibers passes through the mesh and on the back forms a loop-shaped second pile, as can be done in a similar manner from knows the well-known tufted weave. Through the subsequent spraying with a seawater- and / or incorporated fusible fiberX chemical-resistant binderIwiru achieved a great durability. Instead of the mesh fabric can also be used with success Press pile made of synthetic fibers can be used.
Der weitere Vorteil dieses Verfahrens besteht darin, daß durch das Durchdringen des Gittergewebes durch dessen Maschen, bzw. des Preßflores durch dessen Fäden diese so verengt werden, daß die Lockerung des Grabensandes unterbleibt und ein Auswaschen verhindert wird, da der Sand kaum noch durch diese Verfilzung hindurchdringen kann. Durch das GM 6.751.947 ist zwar bekanntgeworden, Abdockmatten mit einem Bändchengewebe zu vernadeln, doch haben die Bändchengewebe von ihrer Struktur- und ilerstellungsweise her nur eino sehr geringe Verschiebefestiglceit. Sie sind für höhere Beanspruchung ungeeignet. Selbstverständlich kann man boi höheren Anforderungen auch 2 oder mehr Gittergewebe oder Preßflore einnadeln.Another advantage of this method is that the Penetration of the lattice fabric through its mesh or the press pile through its Threads these are narrowed so that the loosening of the trench sand does not occur and washing out is prevented because the sand can hardly penetrate through this matting can. It has become known through GM 6,751,947, undocking mats with a ribbon fabric need to be needled, but the ribbon fabrics have the structure and the way they are made only a very low resistance to movement. They are for heavier use not suitable. Of course you can have 2 or more with higher requirements Needle mesh fabric or press pile.
Einc zweite Weiterentwicklung der Grundidee besteht darin, auf der Rückseite der Flore eine Bahn aus Kunstschaumstoff durch Vernadelung der Chemiefasern durch diesen Schaumstoff hindurch anzubringen, wobei man zum Schutze des Schaumstoffes noch ein Gittergewebe aus verschweißten Chemiefaden odor einen Preßflor aus Chemiefäden mit vernadeln kann.A second further development of the basic idea is based on the The back of the pile is made of synthetic foam by needling the man-made fibers to attach through this foam, with one to protect the foam Another mesh fabric made of welded chemical thread or a press pile made of chemical threads with needling.
Da der Sc1iaumstoff offenzeilig ist, kann das Wasser zwar durchtreten, jedoch koin Sand. Er wird sicher zurückgehalten. Das hat besondere Bedeutung, wenn diese Flore zum Schutzo von Entwässerungsgräben benutzt crden sollen. Dns vom Land her zum Entwässerungsgraben strömende Wassor kann keinen Sand mehr mitreißen, wodurch das Zuschwemmen der Entwässerngsgräben sicher vermieden wird.Since the fabric is open-lined, the water can pass through but no sand. He will be held back for sure. That has special meaning when this pile should be used to protect drainage ditches. Dns from the country The water flowing towards the drainage ditch can no longer carry away sand, which means that the flooding of the drainage ditches is reliably avoided.
Eine dritte Ausführung sieht vor, den lockeren Chemiefaserflor ganz in Kunstschaumstoff einzubetten, wie dies In Fig. 4 dargestellt ist. Der Flor hat hier slie Aufgabe, den Kunstschaumstoff reißfest zu machen, während der Schaumstoff die Sicherung der Böschungswand überninunt.A third version provides for the loose synthetic fiber pile completely to be embedded in synthetic foam, as shown in FIG. 4. The pile has The task here is to make the synthetic foam tear-resistant, while the foam securing the slope wall.
Es besteht weiterhin die Möglichkeit, den Flor aus mehreren übereinanderliegenden Faserschichten vcrschiedener Faserfeinheit, Faserart und Faserdichte herzustellen, wodurch die einzelnen Faserschichten eine unterschiedliche Filtorwirkung aufweisen.There is still the possibility of the pile from several superimposed To produce fiber layers of different fiber fineness, fiber type and fiber density, whereby the individual fiber layers have a different filter effect.
Auf den Einbau von Gittcrgeweben kann verziciitet werden, wenn man don Preßflor mit rinder bedruckt mittels Walzen, die eine Reliefoberfläche aufweisen, so daß die Bindung punktartig oder in Itomben, Quadraten oder sonstwie erfolgt. Mehrere derartig gebundene Preßflore ergeben ein Labyrinth mit großem Rücklialtevermögen (Abb. 6).The installation of mesh fabrics can be dispensed with if one don Preßflor printed with cattle by means of rollers that have a relief surface, so that the binding takes place in dots or in itombs, squares or in some other way. Several such tied piles result in a labyrinth with a large amount of return capacity (Fig. 6).
Selbstverständlich können die Flere zusätzlich nach Zusatzpatent (Akt. Zch. P 1.800.243.2) profiliert sein, um dadurch eine weiter Steigerung dor Zug- und Reißfestigkeit und der Filterkraft zu erhalten.Of course, according to an additional patent (file no. Zch. P 1.800.243.2) should be profiled in order to further increase the traction and to maintain tear resistance and filter power.
